1 Claim. l

The present invention relates generally to holding devices, and moreparticularly to a readily releasable handle construction findingparticular adaptation to solder, paddles, reversible files, and thelike.

An object of the present invention is to provide a novel releasablehandlev construction and its adaptation to solder paddles, reversiblefiles, and the like.

Another object is to provide a novel releasable handle constructionwhich is firmly anchored-t the working portion of the device to which itis applied when in operating position in respect thereto in a mannersubstantially eliminating relative lateral movement.

Other objects are to provide a novel handle construction for solderpaddles, and the like, which is readily and easily applied and removed,which is inexpensive to make, which is adapted to render long servicewithout requiring anymaintenance, and which may be applied to andremoved from a working member with minimum instruction.

The foregoing and other object and advantages are apparent from thefollowing description taken with the accompanying drawing, in which:

Fig. 1 is a plan view of a handle construction formed in accordance withthe teachings of the present invention applied to a. solder paddle;

Fig. 2 is a side elevational view thereof;

Fig. 3 is an enlarged vertical transverse crosssectional view on theline 33 of Fig. 2, portions being shown in end elevation;

Fig. 4 is an enlarged fragmentary longitudinal vertical cross-sectionalview taken on substantially the line 4-4 of Fig. 1;

Fig. 5 is an enlarged transverse vertical crosssectional view onsubstantially the line 55 of Fig. 1;

Fig. 6 is an enlarged fragmentary plan View of the recessed portion ofthe solder paddle which receive the handle construction;

Fig. 7 is an end view of the solder paddle looking towards the open endof the handle construction receiving recess; and

Fig. 8 is a fragmentary enlarged longitudinal vertical cross-sectionalview through the attaching end of the handle construction, the hingedclamping or jaw member being shown in released position.

Referring to the drawing more particularly by reference numerals, I0indicate generally a solder paddle incorporating a handle construction[2 and a paddle or work member I4 includ ing the concepts of the presentinvention.

The handle construction 52 includes an attaching flat-bottom base memberit, formed integral with which is ta hand-grip supporting arm it towhich is secured a hand-grip member 28,

preferably of Wood, by suitable screws 22. The hand-grip supporting armI8 includes an arcuate neck portion 24 formed on an arc of ninety degreeso that the hand-grip member 20 is disposed in an offset plane parallelwith the work member l4.

The attaching base member It includes an integral dependingtransverseflange orstationary jaw 26 which forms an acutev angle with the bottom28 of the-member l5. Also formed integral with the member I5 is. alongitudinally extending boss 35 having a threaded longitudinallyextending well 32 which receives a suitable screw 34 having a knurledhead. A movable jaw member 36 is pivotally mounted. on a pin, 33.supported by a central hinge leeveMl formed-integral with the arcuateneck portion 24. The jaw member 35 includes spaced. integral hingesleeves 42 between which is disposed the hinge sleeve ie. The movablemember 36 also includes an integral flange 44 whichis at substantiallyninety degrees thereto. Between the flange 44 and its hinge connection,the movable member 36 includes a slot 48 through which the screw 34extends. It is manifest that the flange 44 is in opposed relation withthe flange 26.

The work member M has a longitudinal recess 48 in the upper surfaceadjacent one end (Figs. 6 and 7). The recess 48 is of shallow depth andis defined by side walls 56. A transverse channel 52 is formed at theinner end of the recess 48 and extends into the body of the work member4 at an acute angle to the surface of the recess 48. Extending beneaththe recess 48 from the end of the work member !4 is a channel 54.

In Fig. 4 the relationship of the handle construction l2 and the workmember I4 is clearly illustrated. The base member I6 fits into therecess 48 with the flange 26 extending into the channel 52. The flange44 of the movable member 35 extends into the channel 54 and is securelymaintained in position by the screw 34, the head of which bears againstthe movable member 36. Both the snug fit of the base member 16 in therecess 48 between the walls 50 and the clamping engagement of theflanges 26 and 44 in their respective channels 52 and 54 insures a rigidconnection between the handle construction l2 and the work member l4.

Manifestly, the handle construction 12 may be quickly removed from thework member M by loosening the screw 34 and pivoting the movable jawmember 35 re arwardly to some such position as that shown in Fig. 8,whereupon the flange 26 may be removed from the channel 52.

As has been pointed out above, the present handle construction l2 findsparticular adaptation to a solder paddle, the Work member of 'which isnormally of wood which becomes burned in its use and requiresreplacementatrelatively *3 frequent intervals. Another application is afiat file of the type which employs an offset handle. Manifestly, thehandle construction is adapted for other uses.

It is apparent that there has been provided a handle construction and aparticular adaptation which fulfill the objects and advantages soughttherefor.

It is to be understood that the foregoing description and theaccompanying drawing have been given by way of illustration and example.It is also to be understood that changes in form of the elements,rearrangement of parts, and substitution of equivalent elements, whichwill be obvious to those skilled in the art, are contemplated as withinthe scope of the present invention which is limited only by the claimwhich follows.

What is claimed is:

A work tool comprising, in combination, an expendable paddle-like workmember, such as a trowel, spatula, or the like, which must be supportedfrom a rearward end for proper use thereof, a longitudinal recess insaid work member extending forwardly from said rearward end, said recesshaving a horizontal plane surface and parallel vertical sides, a firsttransverse channel formed at the forward end of said recess andextending downwardly and rearwardly therefrom, a second transversechannel formed at the rearward end of said work member and extendinghorizontally forwardly therefrom, a handle construction releasablysecured to said work member including a base having a lower horizontalplane surface and parallel vertical sides snugly disposed 3 in saidrecess thereby eliminating relative lateral movement between said workmember and said handle construction, said base including a transversehook portion extending downwardly and rearwardly from a forwardlydisposed end thereof, said hook portion engaging a wall of said firsttransverse channel in said work member, a handle grip support extendingupwardly and rearwardly from said base, a member pivotally connected tosaid grip support, said pivotally mounted member having a transverselyextending flange releasably engaging a wall of said second channel insaid work member, and a screw extending through said pivotally mountedmember and anchored in said base for drawing pivotally mounted memberinto position engaging a wall of said second channel to secure saidhandle construction on said work member.
